TACK OR NAIL HAMMER.

SPECIFICATION forming part of Letters Patent No. 609,672, dated August23, 1898.

Application filed May 25, 1897. Serial No. 638,139. (No model.)

To all whom it may concern:

Be it known that I, GEORGE ERNEST HAS- ZINGER, of Vicksburg, in thecounty of Warren and State of Mississippi, have invented certain new anduseful Improvements in Tack or Nail Hammers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to hammers having an automatically-operatingtack-feeding attachment; and it consists of the details of constructionand arrangement, which will be more fully hereinafter described andclaimed.

The object of the present invention is to provide convenient means inconnection with a hammer-head for readily setting a tack in position fordriving by a simple mechanism operated from the handle of the hammer,the several parts being strong and durable and easily and readilyapplied and comparatively inexpensive in the costof manufacture.

In the accompanying drawings, Figure 1 is a perspective view of a hammerembodying the invention and showing a loading-fork at one side adaptedto be used with the device, all of which embody the features of theinvention. Fig. 2 is a side elevation of the hammer embodying theinvention and broken away at parts to show the interior construction.Fig. 3 is a detail perspective view of the feeder attachment and itsoperating parts disconnected. Fig. 4 is an enlarged sectionalperspective view of the end of the hammer, showing the feedingattachment in connection therewith and slightly turned to one side. Fig.5 is a detail perspective View of a portion of the feeder and theretaining springfinger coacting therewith. Fig. 6 is a detailperspective View of the rear end of the hammer-handle broken away toshow the interior construction. Fig. 7 is a detail perspective view of aslightly-modified form of the feeder, showing a spring-clamp inconnection'with the cap on the foot thereof. Fig. 8 is a detail viewshowing the pivotal or hinged connection of one of the parts.

Referring to the drawings, wherein similar numerals of reference areemployed to in dicate corresponding parts in the several views, thenumeral 1 designatesa handle which is hollow and open at one side, as at2, and provided with a suitable form of head 3, with an opening4extending from one side to the other in line with the upper portion ofthe handle, and a lower circular opening 5 adjacent to the impacting endof the hammer. Pivotally applied to the handle 1 is a wire lever 6,having a rearwardly-extended inclined pressure end 7 and a depending arm8, which has the rear end of an operating-rod 9 movably attachedthereto. The said rod 9 passes through a guide 10 on the lower side ofthe handle and is encircled by a coiled spring 11, which bears againstthe said guide at one end and is attached to the said rod 9 at theopposite end. The outer end of the said rod 9 is formed into a loop andbent at a right angle, as at 12.

Extending through the circular opening 5 in the head of the hammer is arotatable spindle 13, which has a twisted flattened screw 14, engaged bythe angular bent loop 12 of the operating-rod 9, and to hold the saidspindle in proper position in the opening 5 a pin 15 passes transverselytherethrough at a slight angle of inclination to allow the said spindleto have a sliding movement. Continuous with or attached to the outer endof the spindle is a feeder 16, having at the foot thereof a recess 17,which opens out at one side, as at 18, and is covered by a cap 19, heldin position by suitable rivets or other fastenings. Within the saidrecess 17 is pivotally mounted a small retention-plate 19, having aspring 20 connected to a projecting car 21 thereof, beyond the pivotalpoint of the same, and tending to throw the said retention-platedownwardly or toward the bottom of the recess 17 The said retentionplate is bifurcated or recessed and has projecting from one side thereofa finger 22, arranged at an angle of inclination and projecting slightlythrough the opening 18 of the recess 17 Extending outwardly through theopen portion 2 of the handle 1 is a flanged channel- 1 plate 23, whichis arranged at an angleof inclination and extends in a downward planefrom the inner side of the opening 4 through the handle and toward theopposite "side from that through which it extends and for a distanceruns longitudinally with the rear part of the handle, being inclosed atits rear end,

and is engaged by a retention spring-finger 24, having an angular bend25 to hold the tacks in the channel-plate when the latter is locked.The, rear end of the said channel-plate within the handle is flared, fora purpose which will be presently set forth.

As shown by Fig. 1, a loading-fork 26 is adapted to be used with thehandle 1 and consists of an elongated tube having a slot 27 extendinglongitudinally through one side thereof. The one end of the saidloadingfork is cut off at an angle of inclination, as at 28, and formsupper lips 29, which are pointed and have a flared mouth 30 between thesame. These pointed lips 29 and flared mouth are inserted in the end ofthe hammerhandle and engage the rear flared portion of the channel-plate23, and in this operation the retention-spring 24 ispressed back, sothat the tacks carried by the loading-fork may freely slide into thesaid channel-plate. The opposite end of the loading-fork is bentupwardly and provided with tack-pulling toes 31, a cross-pin 32 beingmounted in the upper portion of the loading-fork adjacent to the toes 31to prevent the tacks from slipping out of the channel 27 at this point.In loading the fork the same is plunged-into a receptacle containing aquantity of tacks and the latter enter through the flared mouth 30 andautomatically position themselves in the channel 27 with the headsthereof on the outer side and the points depending toward the interiorof said fork. The cut-away portion 28 of the fork facilitates theunobstructed entrance of the tacks into the channel 27 and permits thelips 29 to be penetrated a considerable distance into a bed or quantityof tacks.

It will be seen that the tacks are delivered from the loading-fork tothe channel-plate 23 with the points downwardly and the heads above, aspreviously set forth, and by this means the heads are fed into the rearportion of the said channel-plate, so that the points of the tacks willextend in a direction nearest the operator when the hammer is held inoperative position. By having the channelplate 23 arranged at an angleand extending from one side of the outer portion of the handle totheinner part of the opposite side of said handle afree anduninterrupted feeding movementof the tacks through the channel-plate isobtained and a greater number of tacks can be loaded into saidchannel-plate in view of the increased length through the inclinedarrangement. Furthermore, this arrangement also properly positions thetacks at their point of delivery to the feeder. At the said delivery endof the feeder is a catch-spring 33, consisting of a small spring-wireattached along the upper portion of one side of the said channel plateand extending diagonally through the'openin g 4 in the hammer-head 3 andover the upper portion of the channelplate at this-point, and at itsouter end the said catch-spring has a transversely-extending finger 34,which is continuous, with an arm 35 arranged at a right angle theretoand formed by rebending the wire at this point. The finger 34: normallylies across the top of the channel-plate and holds the tacks in positiontherein against accidental disengagement while the feeder 16 isoperating to set a tack in position or after said feeder has receivedone tack from the outer end of the said channel-plate. The saidchannel-plate is also formed with a projection 36, over which the arm 35has play, and said projection is engaged by the finger 22 to raise theretention-plate in the recess of the feeder to permit a tack-head topass thereunder, when the feeder is returned and its recess alines withthe outer end of the channel-plate 23. When the said feeder has itsrecessed end moved into alinement with the channel-plate 23, one sidethereof strikes the arm 35 and presses it back, so as to clear thefinger 34 from the channel-plate and permit a tackhead to fall into thesaid recess of the feeder, and the moment the said feeder is moved awayfrom contact with the arm 35 the finger 34: and the said arm move acrossthe top of the channel-plate and hold the tacks in the latter againstmovement until the feeder again returns to receive another tack. At thesame time the retention-plate in the recess 17 of the finger clamps thetack in position, and to accommodate the movement of the tack withoutfriction a recess 37 is formed in the head of the hammer and hasaslightlycurved contour. The said hammerhead is also formed with thefurther recess 38 on the opposite side, which receives the outer end ofthe spring-wire having the finger 34 and arm 35 thereon when movedlaterally. The cap 19 is also formed with a recess 39, through which theshank of the tack projects, and when the feeder is thrown entirelyaround to place the tack in position its end is located in advance ofthe impacting end of the hammer-head.

To compensate for the difference in the size of tacks, a regulator isprovided for the feeder 16, and consists of a pin 40, which isadjustably mounted in the said feeder 16 and-is engaged by a set-screw4.1. This pin regulates the distance the feeder stands out from thehammer-head when closed in thereover by throwing the foot outward ordrawing it in relatively to the channel-plate 23. This adjustment ispermitted through the slight movement of the spindle 13 in thehammerhead, and in the latter a socket 41 is formed, into which theinner end of said pin 40 falls to prevent a rebound of the feeder. Tolimit the outward movement of the feeder, the 11ammer-head is providedwith a shoulder 41 against which the feeder strikes when thrownoutwardly.

In Fig. 7 a spring-clamp 42 is applied to the cap 19 of the feeder andis adapted for use in putting up bill-posters and to hold a sign at anelevation and at the same time start the tack thereover through themedium of the feeder. The handle 1 at its front portion adjacent to thehead 3 is supplied with a wood filling 43 to strengthen the handle atthis point to provide a firm connection for the head of the hammer. Theangularly-bent loop 12 of the rod 9 travels backward and forward overthe screw on the shank 13 and operates in one direction to throw thefeeder around over the impacting end of the hammer-head and in theopposite direction to close the said feeder inwardly in line with thechannel-plate 23.

A further advantage in the arrangement of the channel-plate as set forthis that in the act of striking or delivering a blow the tacks slip morereadily to the feeder by dragging on either side of the slot or oneither side of the shanks of the tacks than they'would do if thechannel-plate were turned over. The latter arrangement would have atendency to cause the heads of the tacks to jam against the top andbottom of the channel-plate While sliding on their heads.

It will also be seen that the. feeder 16 has two movements. It firstmoves forward and then turns around, said forward movement beingnecessary to overcome in part a rebound on the return stroke.

It will be understood that the handle of the hammer is preferably madeof sheet metal, with the joint thereof on top, so that the channel-platecan be put in place before clos ing the'hammer-handle, also that theform of the channel-plate may be changed, if desired.

The device as an entirety is exceptionally convenient for many useswhere tacking or fastening devices are necessary.

It will be understood that the dimensions of the device may be varied atwill and that many minor changes in the details of construction andarrangement of the several parts'might be made and substituted for thoseshown and described without in the least departing from the nature orspirit of the invention.
